or other vessel.

" ble of successfully withstanding 'rough u with the cross head-in amount of gasoline or other liquidin a tank i It is al purpose ofmy inventionl to provide a gasoline gauge by means of which the amount of gasoline or other liquid inl ai tank 'or other vesselcan be accurately determined and; further, a gauge presenting structural characteristics which permit the production of a gang-eef minimum cost; apfgaugecapausage ,and a gauge consisting of aininimum number .of parts', easilyand quickly assembledand disassembled ina manner to permit the ready substitution ofv new parts should the old become worn or broken.

I will describe only one form' of liquid gauge embodying my invention and will then point out the novel features lthereof in'claims. v

Referring specifically to'th-e drawings, my invention, in',v its 'present embodiment, comprises a pair of tubular bodies 15 and 16, respectively,=fformed of metal or othersuitable Vmaterial and arranged one above the other in end to end realtion. At their confronting ends the two bodies are exteriorly threaded to be engaged by a connecting sleeve 17 which permits of the quick connecting of the two bodies and the rigid maintenance of the saine in end to end relation.

rlhe lower body 1G is formed at diametrically opposed points with lelongated opening indicated at 18 which constitute windows through which a tube 19 formed of glass or other suitable material may be ob- SelVed- This tube 19 is of such external diameter aste-snugly fitlwithiiiv the bod-yA 16, the lower end" of the body being eX- teiiorly threaded to recevie a fcup-shaped cap` 20, and' a. yrubber gasket 21V being intenl posed between v the cap and the lower end of theftube19'toform a seat for such tube to prot-ect the latterl against' brez'i-kag'e;v Thev i cap 2() is pr'ovidedfwithv a conical port 22 thro-ugh which gasoline or other liquidismay enter or leave the tube 19, and this port is controlled yby a conical valve 23 movable/ver-l tically within the tube to occupya closed l position, as Vshown in Figuref2, or anopen position, as shown 1n Figure.

The valve 23 is capableof being moved y to either open or closed position-withl respect tothe port 22fthrough the medium of arrod 24 with-in the tube 19` which is operatively connected to the valve by a turnl buckle threadedly engaging. the rod, and the stem 26- of' the valve. This turn buckle Y25 also functions tol allow. of .a longitudinal ,y

adjustmentl of the valve on the kro'd so as ,to insure the proper seating oryunseating of the valve whenithe rod- 24 is manually ac!v Asclearly shownlin Figure 2, the rod'-` 24 extends upwardly through the4 upper `body 15 an'dthrough a cap' 27 threaded on andl closing the upper' endofthe body 15. Beneath the cap`27the rod 'isv provided with a collar 28 and interposed between the Cap and colllarl is an expansible spring 29 which functions to urge the rod downwardly seas tonormally maintainthe valve 23 in closed` position with respect to the port 22. The

rodv 24 is'adapted toI be lifted manually lagainst theI action of the springk 29 by a llooped'handle 30 connected at its ends to cross Yhead 31 which loosely receives the Vrod 24 but is confined against displacement therefrom vby ai nut 32 and av washer y33. The mounting of the cross head 3101i the rod 24 is-suclr` as to allow rotational'` movement thereof to occupy the position shown in solid lines in Figure 1 when the rod 24 is vin its lowermost position, or to occupy the position shown in dot and dash lines inl Figure 4 when the rod is in its uppermost position. In this latter position, the cross head engages a pair of projections 34 formed on the cap 27 so as to maintain the rod in elevated position against the action of the- .spring 29 and to thereby hold the valve 23v in open position. p y

To guide the 'rod in 'its vertical movement e breakage, inter-y 'gas'ket 3 5janda leathergorfy other suitable l i" formfof soft gasketl 36.;kv As'cleailyshown" in Figure 3, the gasket 36is"in engagement' Withthe upper endof the tube 19,` andvboth fof I thegaskets Vare formed with openings through 'which tlierod 24fis'free tofinove Inlpractice, Vthe y lovver end of Vthe gauge is i ysubmerge'd Vto'hthe extreme bottoni Vof the .liquid'tolbe measured, and With'the valve p 23 in open position, theliquidflis freeto fiovv` Tinto the tube 19 tol a.'fleve 1. `corresponding to thelevelifof the liquid inthe lt'anl; or other Container.. `Byno vv rotating the' cross head f 3 1 todis'engage 'theprojcctionse/l, the spring 2 9 "may function Vto'i'ieturn thefvalve 23 to fclosed f'position, thus` 1 trapping the liquid 'Within the tube. jBy 'now removingnthe inl`,stru1nent from the liquid and observing the :il i level'` of the-fliquidin the tube, the amount `of'liquid contained fin the tauk'can be 'de'- termined.' lTo accurately determine the i amountof. liquid inthe tube Iv have provided a strip 37 ofA metal or Vother suitable ma'- vterial detachably secured in" any suitable manner kto, the body 16, andffthisjstrip isv graduatedfso that-thejexa'ct amountv` of li Vuid containedin thel't'ube `can bedetermine Although* Iffhavej/*hereinishovvn and described only onev form "of'rliquidV gauge vemr. bodying my invention, it is to 'be' understood thatvariouschanges 'andnodifications may be-madejther'ein Without departing from the i :spirit of the invention-.;and'the spiritV and scope ofthe appended claims. f
